叶面微肥对谷子生长发育及产量的影响

摘要：本试验选取海心花、喷乐增、藻力素、富活素、海藻素、禾神元生物菌剂6种叶面水溶肥对谷子孕穗期进行叶面喷施。结果表明：6种叶面微肥处理的谷子的株高、茎粗、光合速率、SPAD值、产量等指标均有明显提高。其中海藻素、富活素2种肥料效果显著，较对照净光合速率增加34.76%、29.09%，SPAD值增加9.37%、9.24%，产量增加20.34%、23.09%。以上结果表明，孕穗期喷施叶面微肥能促进谷子的生长发育，提高谷子产量，以海藻素（N5）、富活素（N4）的效果最佳。

Effects of foliar micro-fertilizer on growth and yield of Millet

Abstract:In this experiment, six kinds of foliar water-soluble fertilizers such as haixinhua, pinlezeng, phycocyanin, fuhuosu, seaweed and heshengyuan biological agent were selected to spray grain at booting stage.The results showed that the plant height, stem diameter, photosynthetic rate, SPAD value and yield of millet treated with 6 kinds of foliar micro fertilizer were significantly improved. Among them, two kinds of fertilizers, seaweed and fuhuosu, have significant effects. Compared with the control, the net photosynthetic rate, SPAD and yield were increased by 34.76% and 29.09%, 9.37% and 9.24%, respectively.The above results showed that spraying oliar micro-fertilizers at the booting stage could promote the growth and development of millet and increase the yield of millet. The effect of seaweed (N5) and enrichment (N4) is the best.
